1. A water treatment system comprising: a first cavitation device coupled downstream to a wastewater source via one or more first cavitation device lines; a filter coupled downstream to the first cavitation device via one or more filter lines; an equalizing tank coupled downstream to the filter via one or more equalizing tank lines; a second cavitation device coupled to the equalizing tank via one or more second cavitation device lines where a flow from the equalizing tank which enters the second cavitation device is modified and reenters the equalizing tank; a first booster pump coupled downstream to the equalizing tank via one or more first booster pump lines; a contact tank coupled downstream to the first booster pump via one or more contact tank lines; a carbon filtration device coupled to the contact tank, wherein the carbon filtration device is integral with the contact tank; a biological treatment system coupled downstream to the carbon filtration device via one or more biological treatment system lines; a second booster pump coupled downstream to the biological treatment system via one or more second booster pump lines; a polishing mass media filter coupled downstream to the second booster pump via one or more polishing mass media filter lines; a granular activated carbon system coupled downstream to the polishing mass media filter via one or more granular activated carbon system feeds; an ozonation system coupled downstream to the granular activated carbon system via one or more ozonation system lines; a reaction tank coupled downstream to the ozonation system via one or more reaction tank lines; a third booster pump coupled downstream to the reaction tank via one or more third booster pump lines; a reverse osmosis pump coupled downstream to the third booster pump via one or more reverse osmosis pump lines; a reverse osmosis system coupled downstream to the one or more reverse osmosis pump lines via one or more reverse osmosis system lines; and a sow tank coupled downstream to the reverse osmosis system via one or more sow lines.
